The FAQs about TPE materials
TPE elastomer soft rubber can be adjusted to appropriate hardness according to the physical property requirements of the product (hardness range Shore 25-90A),
Diene transparent TPE, diene TPE is mainly an isomer of natural rubber, so it is also called thermoplastic trans-natural rubber. Although its heat resistance and mechanical strength are not as good as rubber, with good transparency, weather resistance, electrical insulation, and photodegradability, it is widely used in shoemaking, sponges, optical films, and other industrial rubber products.
TPE, TPR overmolding layer thickness. In most overmolding applications, a wall thickness range of 1.5-3.0mm will ensure good adhesion. If the TPE layer is too thin, injection molding is difficult, adhesion strength is low, and hand feel is poor. If the TPE layer is too thick, on one hand cost is higher, and on the other hand defects such as shrinkage and bubbles are prone to occur.
Rubber TPE material
TPE overmolding, as the name suggests, is to overmold TPE soft rubber material onto other materials.
Transparent TPE is used in appliance housings, handles, and grips, etc. It exhibits very good hand feel, is anti-slip and labor-saving, and is easy to color and process. It also has a wide design space.

Rubber TPE material
TPE material has good fluidity and is mainly injection molded.
Since any impurity in TPE material may affect the transparency of the product, care must be taken to ensure sealing during storage, transportation, and feeding to keep the TPE raw material clean. Especially if the TPE raw material contains moisture, it will cause deterioration after heating, so it must be dried. During injection molding, a drying hopper must be used for feeding.
Transparent TPE, specifically, is a thermoplastic elastomer, while TPR, translated from English, is strictly called thermoplastic rubber. This is the most basic difference. TPE is generally modified from SEBS base material, while TPR is modified from SBS base material.
